Well I can understand the "they're measuring different things" bit - much as people who use the Freestyle Libre shouldn't get too upset when it doesn't exactly match their fingerprick readings, because they are measuring different things. Interstitial fluid tracks behind blood glucose, may miss extreme peaks and troughs and can also be influenced by local conditions such as pressing on the sensor. But since blood glucose is constantly changing, and in any case is not exactly the same at every point in the body at any point in time, you just have to understand the limitations of each.
I'm a bit puzzled by him saying BHOB is a waste product, though - I thought it was the main form the body used, and it's in the blood because it's being transported round the body to all the parts that can use it. I'd like to hear more detail on that, if it's available.
Also be aware that the new software gives you the option of reporting in either Ketnonix Units or ppm (parts per million) and I surmise you need to choose the correct one for your device. Mine reads in ppm, but the dial @Vampire showed is in ketonix Units. Don't know what the correlation is.....
I've just blown 19 ppm on my ketonix and my blood level was 1.0
I'm finding the flashing lights a bit confusing..... I've configured mine so that Green starts at 4ppm and Yellow at 17, with Red starting at 30. NK is supposed to be between 4 and 30ppm, so I'm basically dividing the NK range equally between green and yellow, with blue being not in ketosis and red being.... are you serious???
I've had a few occasions when the number has gone into the yellow range, e.g. 19, 21 - but the flashing lights were still green. And as soon as you take it out of your mouth so you can count the flashes, they start reducing. Maybe I'll get used to it.
